Yes, they take AAA batteries, I get the best results with Energizer. They also EAT batteries like crazy - always have extra on hand and take them out when you are done using them.

It uses the 9 volt batteries, you could use rechargeable 9 volt if you wanted to and they were available.

They take 9V batteries, in the transmitter/headsets. They don't last too long - and kids tend to forget to shut the unit off when they are done.

I'm sorry I do not understand your question. Are you asking what brand they are? They are great batteries and last a while. I would recommend them to anyone for the price and quality.

They require batteries, I gave them as a gift to my son in law, but I believe they run on 3V batteries.

Regular batteries, but don't waste the batteries. Not a good product. Poor performance

They use any AA batteries but you have to re-charge the batteries with a separated charger. The system does not charge.

I can't remember what batteries they use, but the batteries come with the candle.

they use the flat CR batteries, I believe they came with batteries and then I went online & bought extra batteries (very reasonable.) Depends on how much you use the candles on how long the batteries last.

It uses CR2032 batteries, a very common calculator battery. We usually get a whole bunch of them since so many small devices around the house use them.

I really don't know. Only the included batteries are used, and they have a short life before requiring recharging.
